INTERCHANG EABLE HEEL FOR BOOTS AND SHOES.

Specification of Letters Patent.

Application filed February 14-, 1906. Serial No. 301,066.

To aZZ whom it may concern.-

Be it known that I, ROBERT BARNES, a subject of the King of Great Britain, residing at N o. 78 Gertrude street, Fitzroy, in the State of Victoria and Commonwealth of Australia, have invented a certain new and useful Imroved Interchangeable Heel for Boots and bhoes, of which the following is a specification.

This invention relates to that class of interchangeable heel for boots and shoes in which a rubber or leather pad is attached to the heel proper and my invention consists in the means I have devised for connecting the two together, and which means permit of the pad being easily disconnected from the heel proper without the use of any tool whenever the pad becomes worn and it is desired to change the pad from one heel to another or to attach a new one.

My invention consists of two parts. That part which is built into the heel proper consists of a narrow flat metal ring which is preferably of irregular outline on its outer periphery and of circular form on its inner periphery. Projecting upwardly from and formed integral with the inner periphery of said ring is a circular collar. In this collar is a slot through which one end of a spring is passed and riveted to the plate. Immediately opposite this slot the collar is cut away, and the metal ring at that point is bent upwardly into an inverted-U-shaped form to constitute a guide for the free end of the spring, which projects slightly beyond the outer periphery of the ring. Upon the inner periphery of the collar are two studs, one on either side thereof and in line at right angles with the spring. Projecting upwardly from the outer edge of the ring are three or more teeth, which are for the purpose of preventing the rotation of the ring and its appurtenant parts when built into the heel proper in the manner well known.

That part of my invention to which is attached the removable pad consists of a narrow flat metal ring of approximately the same shape as the metal ring before referred to. Projecting downwardly from and formed integral with the inner periphery of said ring is a circular collar of slightly smaller diameter than the collar before referred to. In said collar and opposite each other are two recesses, and between and in line with these is a U-shaped metal trough. On the outer periphery of the collar and near the top thereof is a horizontal groove or race extending all around said collar. The inside of the collar is filled with vulcanite up to and level with the top thereof, the vulcanite being afterward cut away between the sides of the trough and in line with the recesses before referred to for the reception of the springforming portion of the part attached to the heel proper. This part of my invention is built into the leather when a leather pad is required or molded with the rubber when a rubber pad is to be used in such a way that the horizontal groove in the collar projects slightly above the surface.

Referring to the annexed drawings, in which similar reference-letters indicate corresponding parts in all the figures, Figure 1 is an elevation of portion of a boot with my invention applied thereto, the heel being in section. Fig. 2 is a perspective view of that part of my invention which is built into the heel proper. Fig. 3 is a perspective view of that portion of my invention which is attached to the heel-pad. Fig. 4 is a plan of Fig. 2. Fig. 5 is a plan of Fig. 3, Fig. 6 is an elevation of Fig. 4:. Fig. 7 is a perspective view of the removable pad, showing the part illustrated in Fig. 3 applied thereto. Fig. 8 is a perspective view of the two parts of my invention locked together.

A represents portion of a boot, showing my invention applied thereto. B is the heel proper thereof.

C is the removable pad.

D (see Figs. 2, 4, 6, and 8) is the metal ring to be attached to and shown in Fig. 1 attached to the heel proper. E is a circular collar projecting upwardly from the inner periphery of said ring. F is a slot in said collar E. G is that portion of the collar which is cut away opposite the slot F.

H is a guide formed by bending upwardly into an inverted-U-shape form a portion of the ring D opposite the cut-away portion G.

I is a spring attached to the ring D by rivet J and passed through slot F, the free end of said spring being free to work in guide H.

K are twostuds, one on either side of the inner periphery of the collar E, the said studs being in a line at right angles with the spring I.

L are teeth projecting upwardly from the ring D and which teeth prevent the rotation of the ring and its appurtenant parts when built into the heel proper.

M (see Figs. 3, 5, 7, and 8) is the metal ring to be attached to and shown in Fig. 1 attached to the removable pad 0. N is a circular collar projecting downwardly from the inner periphery of said ring M, and O are recesses opposite each other in said collar N. P is a U-shaped metal trough between and in line with said recesses O.

Q is the horizontal groove extending all around the collar N.

R is the vulcanite inside of the collar N.

S is the groove in the vulcanite It.

To connect the removable pad C with the heel proper, B, the pad 0 is placed at right angles to the heel proper, B, so that the studs K on the inner periphery of the collar E are in line with the recesses O and the groove S. The pad 0 is then pressed downward, compressing the spring I until the studs K on the collar E are in line with the horizontal groove or race The removable padC is then revolved until it is in line with the heel proper, B, when the spring I engages with the horizontal groove S, thereby locking the heel proper and removable pad securely together. To disconnect the two parts, the spring I is compressed and the pad 0 revolved until the studs K are again in line with the groove S, when the pad is out of engagement with the heel proper.

Having now fully described and ascertained my said invention and the manner in which it is to be performed, I declare that what I claim is- In interchangeable heels for boots and shoes, the combination of a metallic ring attached to the removable heel portion, a circular collar carried thereby and having a groove in the periphery thereof and recesses leading from the upper edge of the collar to such groove, means permanently secured to the shoe for engaging the collar to hold the removableheel, attached thereto, in place and means to prevent it from turning.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

ROBERT BARNES.
